Question

До турбазы автобус шёл 2 ч со скоростью 68км.ч. Затем водитель увеличил скорость на 15 км.ч и ещё через 2 ч автобус приехал на конечную станцию. Сколько километров проехал автобус за это время?

Answer 1

1. 68+15=83 км.ч.
2.68*2=136 км.
3.83*2=166 км.
4.166+136=302 км.

Answer 2

Calculation of the Distance Traveled by the Bus

To calculate the distance traveled by the bus, we need to consider the two different segments of the journey: the first segment when the bus was traveling at a speed of 68 km/h for 2 hours, and the second segment when the bus increased its speed by 15 km/h and traveled for another 2 hours.

Let's calculate the distance traveled for each segment separately and then add them together to find the total distance traveled.

1. First Segment: - Speed: 68 km/h - Time: 2 hours

To calculate the distance traveled in the first segment, we can use the formula:

Distance = Speed × Time

Substituting the given values, we get:

Distance = 68 km/h × 2 hours = 136 km.

2. Second Segment: - Speed: 68 km/h + 15 km/h = 83 km/h - Time: 2 hours

Using the same formula as above, we can calculate the distance traveled in the second segment:

Distance = Speed × Time

Substituting the given values, we get:

Distance = 83 km/h × 2 hours = 166 km.

3. Total Distance Traveled: - Distance in the first segment: 136 km - Distance in the second segment: 166 km

To find the total distance traveled, we add the distances of the two segments together:

Total Distance = Distance in the first segment + Distance in the second segment

Substituting the values, we get:

Total Distance = 136 km + 166 km = 302 km

Therefore, the bus traveled a total distance of 302 kilometers during this journey.
